Power rectifier system introduction:
AC DC rectifier system is consisted by one rectifier module or multiple rectifier modules and monitor modules. The power of rectifier systems can be different by different quantity rectifier modules.
This rectifier system converters high voltage AC to DC24V or DC48V use for special DC equipment load. High efficiency>96%.
Remark: Some rectifier system need rectifier modules, monitor and distribution; Some system only need rectifier modules. AC-DC rectifier system can supply DC power for DC load and charging for battery at the same time.
Features of 48V Rectifier Module SET1648
1, High efficiency. 48VDC rectifier telecom modules used soft switch technology, while load rate10% then efficiency can be 91%, 50% load rate the efficiency can be above 96%.
2, Circuit of the 48VDC Rectifier telecom modules have two part, one is PFC adjust; The other is DC/DC transformation. All technically make the wide input voltage range (85V-290V).
3, With stepless current limiter technology, output current is continuously adjustable.
4, Adopted stepless temperature control speed, it can reduce power consumption and prolong the life of the fan.
5, Digital signal collection via internal RS485 bus; RS232 interface for remote operation. 3 alarm dry contact alarm: Emergency alarm, main alarm, general alarm.
6, The 48V rectifier has passed the inspection of the Ministry of Information Industry Quality Supervision and Inspection Center.
7, System configuration is flexible and convenient, easy to expand; N +1 redundant power supply, can be configured according to customer demand.
8, 2U height, light weight, High power density.
9, Sharing Load, Equalized-current imbalance ≤ 3%.
10, Controller MCU.
Features of Monitor module SETM16
1, Output load shunt have functions of short-circuit and over-current protection. Shunt capacity can be adjusted according to user requirements
2, Battery input with fuse breaker or MCB, has functions of short circuit, over-current protection and alarm. Fault condition can be detected.
3, The software is easy and safe to operate.
4, Parameter setting is comprehensive and detailed, such as Low machine time setting, Temperature compensation setting, Overvoltage-under voltage setting, Recovery voltage etc.
Contents of Monitor module SETM16
1, LCD display: Blue background, white information, including date, system voltage, load current, battery current, input voltage, load condition (connect or disconnect), battery temperature, charge condition, etc.
2, Through the system menu set the relevant parameters, including System voltage setting, Charge Management, Alarm limit setting, Low pressure breaker setting, time setting, modify password, language selection, module configuration, etc.
3, Alarm and recording functions: Through RS485 connect and communicate between rectifier module and monitor module. There are 3 types of alarm, emergency alarm, the main alarm, general alarm.
